A few Hotkeys that I think are really useful, but aren’t talked about much are. Shift+Ctrl+Tab to bring snapping options to your cursor. Shift+Tab to toggle snapping. Ctrl+Alt+q for quad view. I like to check lock on n-panel, view tab, quad view panel. Also when animating, in dopesheet and graph editors I like to check Show Sliders under view menu. You can also switch between dopesheet/timeline editor and graph editor by pressing ctrl+tab with mouse cursor over those editors. If you are dealing with a lot of objects that you need to organize into collection the Collections manager addon that comes with Blender is very helpful. Same with Material utilities addon.
Also in shader editor you can drag from an output or input to the background and it will give you a list of nodes that can be used for that output/input. Sometimes this is faster than using the shift+a.
